Гальваническая развязка
Компания Analog Devices выпускает широкий спектр интерфейсных компонентов, включая решения для многих промышленных стандартов передачи данных. Мы также предлагаем цифровые изоляторы, изолированные трансиверы и изолированные АЦП на базе удостоенных наград технологий iCoupler® и isoPower® для реализации гальванической развязки без многих ограничений, присущих оптопарам. К другим интерфейсным компонентам, выпускаемым Analog Devices, относятся контроллеры клавиатуры, преобразователи уровней и высоковольтные компоненты защиты, включая устойчивые к “защелкиванию” ключи и мультиплексоры с защитой от повышенного напряжения.
